MASS; SAID BAUER ASSIGNOR To SAID WATsoN AND HALL;

com-me FOR-WIRE PREPARAIN'ORY To DRIAWING.

SPECIFICATION forming part of Letters Patent No. 284,345. dated September 4, 1883i CHARLES. S. HALL, and PAUL BAUER, all of the city and county of Worcester and Com- Inonwealth of Massachusetts, have invented certain new and useful Improvements in the Art or Process of Drawing Wire; and we do hereby declare that .the following is a full,

clear, and exact description of the same.

Our invention relates to the application of apeculiar anti-friction coating or lubricant to the surface of wire or wire rods, to facilitate their reduction in size 5 and it consists in the use of chlorine to unite such substances as are suitable for coatings or lubricants to the wire which is to be drawn or reduced.

istry that chlorine has a powerful affinity for,

It is well known to those skilled in the art that when wire'is to be reduced by drawing 'througha hole in a die plate there must be some substance 011 the wire'which shall come between the surfaces of thetwo metals viz., the wire and the die-plate-in order to lessen the frictionand to prevent the die from scratching the wire.

It is well known to those versed in chenr the metals. We. have made use of this property by employing chlorine, either ,free or in its compounds, to impart valuable adhesive qualities to substances which are suitable for coatings or lubricants for wire which is to be drawn or reduced in size. A

Our composition or coating is composedof the following substances mixed together:

about four pounds of chloride of lime, six

gallons of water, six: gallons of pulp or paste made from potatoes or any vegetables of similar qualities or constituents, or made from any kind of flour or from starch, and three gallons of milk of lime. f

The proportions of the ingredients of our composition may be varied somewhat, if deby any other coating known to us.

while other coatings are not adapted to both Application filed February 12, 1883. (No specimens.)

sired, as we do not wish to limit ourselves strictly to the proportions above given.

It is not necessary to use all of the above- 5 named substances for a coating, aschloriiie and water, in combination with oneor more of the other substances named, are all'that are necessary to constitute a coating that will work well but we prefer to use the composition as given above;

-As chlorine is not suited for transportation as a gas, we have found it more convenient to use one of its combinationsviz., chloride of lime, or bleachingpowder. Other compounds 5 5 of chlorine may also be used-as, for instance, hypochlorite of lime, the chlorides'of calcium, soda, and potash, hydrochloric acid, and chlorine-water.

By the use of our invention wire rods or wire can be drawn heavier drafts, and a greater number of drafts, ithout reannealing,than

It can also be used successfully on fine sizes of wire,

s coarse and fine sizes. y

We disclaim the use of the compound of chlorine with sodium or common salt with or without lime as a coating.

Having described our improvements in the art or process of drawing wire, what we claim herein as new and of our invention, and do sire to secure by Letters Patent, is-

A coating for wire preparatory to its being H drawn, composedof chloride of lime, water, pulp or paste, and milk of lime, in the pro portions substantially as above described.
